To uit rif/ioni it may Conner/z.'

Be it known that, l', b'olncN (l. Moxlnano. a citizen ot the United States, residing at Leadville, in the county. of Lake and State nel. dritt.l or other iindergrroundexcai'ation.

so as' to avoid the possibility of the charlie YfallingT upon the runway or track t'or the truck and therel'iy hlm-king` the exit for the saine within the, tunnel, drift.. er the like.

Another object of the invention is the provision ot' a truck oi this chararter wherein the charge'when delivered thereto will he lnztl'ed on its entrance into the trueli' through the medium ot a g/aeltiug eonfined between the inner and outta' walls ol" said trurk thereby avoiding tlainagrilr;r olE ilu` saine. resultant troni the vella-ity of the chargesl when blasting vthiI saine. the truck lit-ing especially designed to` prevent the chal-ges troni falling' upon the road-hed over which the said truck travels when enterin y or leavinvention consists in the eonstriuftimi, eonibinat-ion and arrangement of par as will be hereinafter more t'ully described. illustrated in the aceoinpanyiner drawings, and pointed out. in the elaii'ns liereunto appended.

vln the drawings: lt`igrure'l is a. vertif'al longitudinal sectional view through 4u tunnel`r dritt: or the like` showing: the lilasty holes in the, end wall thereof and the truck eony structed in a -c n'dance with the invention View of the main and trailer trucks. Fig. 3 is a `vertical longitudinal sectional View therethrough. Fig. 4 is a sectional view on the line l-l of Fig. 2. Fig. 5 is a sectional View on the line :SM5 of Fig. 2.

Similar reference characters indicate corresponding' partsy throughout the Several views in the drawing.. v

Referring to the drawings by numerals 5 'lesignares generally a tunnel, 6 the closed inner end thereof, and 7 the bed, the inner end (i heing'formedwith blast; holes 8, constructed in the ordinary `Well-known manner. The bed 7 of the tunnel has embedded plan which are supported the track rails 1,0, which are fastened thereto in any suitable manner, and are laid so as to extend longitudinally within the tunnel 5 in proximity to the inner closed end wall 6 thereof for the guiding of trucks presently described thereinto.

Loeated a considerable distance spaced from the inner'eud Vall G of the tunnel 5 interiorly thereof is a doorway 1l in which is swingingly mounted a door or gate 13.

the saine being suspended upon a hinged pintle 14 from the head of the doorway, which latter is removably held in iosition within the tunnel thrijmgh the lnediuin of wedge inernhers l5 which are driven between the edge at the head ot' the doorway 1l and the top wall of the tunnel. the wedges'heing connected to the door or gate t?, through the medium of u cahle tti so as to avoid the possihility ot the loss ot' the wedges when disengaged troni hetweenl the doorway and the top wall .of the tunnel or when not in use. Movahle. over the rails l() ot' the track are charge reei'fiving trneirs and l. the 'former comprising a forwardly inclined hed 'l'l' supported upon front and rear axles lttund 19 respect.ively` having journaled thereon track Wheels 20, the wheels upon the t'ront axle 1S being` of considerable less Adiameter than. the wheels supportedh upon the rear axle 19., sog-hat the said truck A will forwardly tip, and supported upon the head 1T thereof is a body 2t including spaced inner and Outer sheet, metalfwalls 22 and 23 and an inter mediate paeliinfr 0l. tlieri-hetween', the paicking helingy eoiny'iosed ot' suitable cushioning material .auch as rags. paper. rubber. corti. or other lil-:e material` so as to ahsorh undue shocks and .iarsot' iinpaet. from the charges in position for receiving the eharr'e on the i tolling thereonto on'the hlastiingof theinner hlasing within Lire tunnel. Fig. 2 is a. top l wall t' ol the tunnel. The body Qliof'th'e '70 therein at intervals the usual cross ties 9 on socket-like extension 25, while thc ,the mcdiumpof a chain coupling 36, whereby the front` end of t-he truck B will extend in .27, the side walls of the body 21 being up- '.tially hopper-shaped i coupled together.

g I 1,062,492 l' truck at its lowerinost end is formed with a -iVhat is claimed is opposite l. ln a 'mine truck, a body having a'resilicnt packing between its inner and outer snrfaccsthroughout the area'tliereot', the said body being forwardly inclined, and a shovellike extension at its lowerinost end.

2. ln a mine truck, a body having a resilient packing between its inner and outer surclevated end is forwardly sloped at 2G and is provided .with a rearwardly extended .lip

wardly diverged with respect to cach other` S0 as to protrude laterally beyond the rails of the track 10 to prevent the chargesl froni falling on the track. The trailer truck -B body being forwardly inclined, Aa shovel-like extension at. its lowerinost end, and a lip projecting outwardly troni the opposite end of the body.

3. ln a mine truek,a body having a resilient packing between its inner and outer surfaces throughout the area thereof, the said body being forwardly inclined, a shovel-like extension at its lowermost end, a lip projectcoinprises a substanbody 28 fol-ined with inner and outer spaced walls 2t) and 30 rcspectively and an intermediate cushioning acking 31 therebetween, the said packing Jeing formed from any suitable resilient ina- .terial and this body 28 is supported upon a horizontal bed 32, having tixedthereto axles 33 supporting front and rear track wheels `34 and 35 respectively, the same being of ing outwardly froin the opposite eno of the u niforin diameters with respect to each oody. and a trailing truck having loose conother und lare adapted to travel upon the nection with said first named truck Whererails l() of the track.

The trailer ti'uck with the rear end of the truck A overlapped by the lip on the first nained truck.

4. In a niine truck, a body having a resilient packing between its inner and outer surfaces throughout the area thereof, thesaid body being forwardly inclined, a shovelelike extension at its lower'inost end, a lip projecting .outwardly'from the opposite' end of the body, a trailing-truck having' loose connection with said first named truck whereby one end of the said trailing truck will be overlapped by the lip on 4the first named truck, and wheels supporting said trucks respectively, and adapted Vto travel upon a tirack. i "L t In testimony whereof I- aflix iny signature in presence of'two Witnesses. i

B is flexibly connected through proximity tothe bodyl 2l of the ltruck A, so thatl the lip 27 will overlap the said for# Ward end of the truck B, and thereby obviate the possibility of the charges falling between the said' trucks A and B when uring the blasting of the tunnel 5, the charges blasted vwill be throw-n backwardly into the said tu4 l and caught upon the trucks Aand B, vwhereby thev said charges may be transported exteriorly of the tunnel in any ordinary well-known manner.

From the foregoing description, taken in connection With the' accompanying drawings, it is thought that the construction and operation of the inventionwill'be clearly Witnesses: understood, and therefore, a more extended M. DWYER,
